't IMPROVEMENT INVIvIAcI-IINES I-'oR PAINTING BARREL-s.

Specification forming part of Letters Patent No. 199,623, dated January29, 1878;` application led 'Mari-.1129, 1877.

V.To all whom it may concern:

. ing Barrels; and I do hereby declare the following tobe a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it pertains to make and use it, referencebeing had to the accompanying drawings, which form part of thisspecification.

My invention relates to devices for painting barrels; 'the revolvingbarrel in contact with brushes andconsistsA inchucks for receiving andmechanism -for bearing the barrell away,

substantially as hereinafter set forth and claimed. In the drawings,Figure l isA a plan view; Fig. 2, a side elevation on the side where thepower is applied.k Fig. 3 is an fend elevation adjacent to the conveyer.Fig. L is a side elevation on the side opposite :the power. 5 isalongitudinal central section, by a vertical plane, containing theaXisvof the barrel; Fig. 6, a central cross section, by a vertical planeperpendicular to the aXis of the barrel; and Fig.` 7, a separate view ofa chuck, which is a variation of my invention. A

.lheV objectof this invention is to paint the @a barrels both upon thebody and end, andperform the operation readily and well.`

A is a barrel -way, upon which the barrels are received. B is the barrelthat is being operated upon. C are the paint-brush rollers. Clare thebrushes upon the said rollers. C2 are` stops, so located with respect tothe rollers that at the time when the barrel comes in upon the rollersthese stops will serve to 'center the barrel in proper position to, beclamped by th'echucks.l D D1 are the chucks. These chucks are providedwith gearteeth ,or co'gs d d', and they, in turn, 'mesh with pinions D24on thesha'ft E.A Y I. F are 'frames which surround the movable chucks.vThe frames F are made to `slide in the main frame of the machine bymeans of guides f', in any suitable manner. The frames F also bear thepaint-troughs F andthe paintbrushes G, which serve to paint the ends of'or out of the barrel. 'Theframes F are likewise connected, by levers H,with the shaftl, and at the pointsv where they embrace the shaft I 'theyare screw-threaded to fit upon the kright and left hand screws on thesaid shaft. The frames F likewise kcarry with them the movable chucks DD1, and the cogs are sufficiently broad to remain in gear withthepinions l)2 as the frames F are moved "in and out bythe levers H asthe shaft I is turned. y

I' is a pulley, attached to suitable shafting, which will enable it tobe thrown readily in gear and reversed in its motion, at pleasure. (Saidcontrivance is not shown, but is too well known to nee-d description,and forms no part of my invention.) y

The object of the pulley l' isA that, when the barrelis in properposition to be chucked, this pulley Iv is thrown into gear, and, beingrigidly connected to the shaft I, it turns the shaft, which, by itsright and left hand screws, drives the tops of the levers H apart, andthey, turning upon the pivots h, force lthe chucks together and clampthe barrel in place. 4When the barrel isproperly chucked the pulley I isthrown out of gear until the bar- .rel ispainted. The pulley I is thengiven a 'reverse motion, which releases' the barrel, and the' chucks arein position to receive the next.

E is the drive-shaft. It has a loosepulley, J, which connects with thedriving mechanism. J is a clutch, and is provided with clutchteeth jl,corresponding `to the small clutchteethj on vthe driving-pulley J. Theclutch J slides on a feather, jl, on the shaft E.

A lever, k, serves to throw the clutch Jiin or out of gear with thepulley J,"`and,f of course,iwhen in gear the pulley J causes the shaftEto revolv On the shaft E, and loosely connected therewith by feathers,so as to slide thereon, are worm-gears L L'. When the shaft E' isrevolved, these worm-gears likewise revolve. Theworm-gears L mesh withpinions g on the topslof the shafts of the upright brushes G, andbevelgears at thebottoms of these 'upright shafts mesh intocorrespondingbevelgears in the horizontal brushes G', and'impart'revolution to them also.

giving both the'brushes motion in the same direction. This, of course,might be effected by a belt passing over pulleys l?, instead of by anintermediate gear mechanism shown.

Y The lever K has a couple of grooves, lo k1,

upon its under surface, the object being as follows: A projecting pin,k2, on top of theV lpinion m passes around through this groove,

k, and in passing farther around passes into the groove k1, and comingto the end of that groove it throws vthe lever K outward suticiently farto release the clutch J' from the pulley J, thus stopping the motion ofthe shaft E, and consequently stopping the revolution ofthe barrel andthe motion of the paint-brushes. The gearing is so arranged that whenthe pulley J is thrown out of gear the barrel shall have been revolved asufcient number of times to become thoroughly painted, andthe brushes Gshall stop with the stops (l2 'in proper position for centering the nextbarrel, and throw all the brushes off from the barrel. Y

. Q is aleVer, poised upon the shaft E, or

upon some other suitable pivot. At the farther end of this lever is afriction-clutch, Q1, which clutch is .arranged to be opened by theupward motion of a lever, Q2. When the lever Q is raised the clutch Q1comes down and clutches the cross-bar It. This cross-bar bears the stopsSat its ends. The object of these stops is to drop down in front of thenext barrel, to prevent its rolling into themachine until the firstbarrel has been painted and discharged. At the other end of the -lever Qare attached the stops S and arms s'.

These stops serve also to assist in centering the barrel.

When it is desired to release the barrel from the machine, the chucksare opened to loosen the barrel. The lever Q is then raised, and thuslifting the stops S' away from the barrel, it rolls out -by itsowngravity. The lever Q is then pressed downward. The clutch Q1 thusraises cross-bar It, with the stops S, from in front of the next barrel.The next barrel then rolls into the machine, and as it rolls in itstrikes the lever Q2, causing it to releasey the clutch Q1, andpermitting the stclips S to fall down infront of the next barre I T isan elevator or conveyer, which receives the barrel B as it rolls fromthe machine and bears it away, and supports it until it has beenpartially dried by a current of warm or cold air, or. in any suitableway.

W is a paint-trough, which supplies the largepaint-rollers. W' is ascraper at y.the side, which removes vthe surplus 4paintbefore the brushcomes in contact with' the barrel; and the brushes are so arranged thatone will deliver the paint while the other will remove the surplus; andin the same way with the brushes that paint the ends of the barrel-fthehorizontal ones deliver the paint and the vertical ones remove thesurplus; and similar scrapers may be provided at the side troughs.

Instead "of employing the movable chucks D, as shown, all solid or in asingle piece, the same may be formed of three or more parts, as shown inFig. 7, wherein V is a rubber 0r other spring, located between thechuckingpiece and that portion bearing the gear or oogs.

l. A barrel-painting machine, consisting of movable chucks for clampingthe k.ends of the barrel, in combination with mechanism, substantiallyas described, for revolving the barrel about its axis, and brushes fordelivering paint to the surface of the barrel as it is revolved,substantially as and for the purposes described.

2. In a barrel-paintingmachine, the combination ofthe movable chucks forchucking the ends of the barrel, mechanism, substantially as described,for revolving the Y same aboutv its axis, brushes for delivering paintto the surface of the barrel, and automatic mechanism for stopping thebarrel when properly painted,` substantially as and for the purposesdescribed.
